Griffith University’s Climate Action Beacon conducted the second of five planned Climate Action Surveys in September-December 2022. The survey discovered what Australians think, feel and do about climate change and related environmental and climatic events, conditions and issues. This report gives details of the background of the survey, as well as its methods, major findings and potential implications. Comparisons are made with findings from the corresponding 2021 survey. The 2022 Climate Action Survey gathered data from two overlapping populations of adult Australians: 1,263 people who had participated in the 2021 survey (repeat respondents); and 2,767 previously unsurveyed people (new respondents). The total 2022 sample comprised 4,030 Australian adults. Although the 2021 participants were representative of the national population, those members of this sample who participated again in 2022 were, on average, nine to 10 years older than both the national population and the remainder of the 2021 survey respondents. In contrast, the recruitment of new respondents ensured that this sample was demographically representative of the Australian population. Unless otherwise stated (i.e., identified as repeat respondents) the 2022 results reported here are drawn from the 2022 new respondents. Two versions of the online questionnaire were used in 2022—one for the repeat respondents and one for the new respondents. The latter questionnaire closely resembled that used in 2021. For the repeat respondents, questions that did not warrant asking a second time in two years were replaced by questions exploring new topics especially related to heat exposure and the 2022 flooding events. Both questionnaires comprised almost 200 single items/ questions, approximately 30 multiitem composite scales and several open-ended questions. Each could be completed in approximately 30 minutes. This is one of the most ambitious climate change surveys conducted in Australia, in terms of sample size, methodological rigour, multidisciplinate input and breadth of coverage. The survey explored different views about climate change; feelings/ concerns about the threat and reality of climate change; knowledge of climate change and information sources used to obtain this knowledge; experiences of extreme weather events, natural disasters (including the 2022 Australian floods) and climate change impacts; pro-environmental behaviours and lifestyles; barriers to engaging in these behaviours and lifestyles; and self-views, worldviews and sociopolitical opinions. We also collected demographic data to reveal details about Australians and climate action.
